Why was the summary for the Shri Sai Satcharitra not written by its original author, Hemadpant?

According to Chapter 53, the original author, Hemadpant, had made a promise to provide a summary to complete the book. However, this did not happen because he suddenly passed away, leaving his work unfinished. The chapter emphasizes that this illustrates a higher principle: 'Nothing happens by one's own will; Baba’s will is more powerful.' Hemadpant's son, Gajanan, later went through his father's vast records and confirmed that the summary was indeed missing from the final chapter materials.
